I've been running CM10.1 nightlies for quite a while and haven't had any serious issues. There was one build that prevented the internal SD card from mounting correctly, but it was fixable in a terminal emulator window. I'd never go back to stock now.

Shoes2468:I was only ever going to install the stock 4.1.2 rom, if I flashed back to ICS would that up the rom counter?

Genuine Samsung firmware should never modify the counter. It only increases if you install something that is modified (e.g. a rooted stock kernel) or completely custom.

If you do install a non-stock firmware, flashing a stock firmware over the top will remove the triangle, but an internal counter will still keep note of the non-stock install.

and found it was surprising easy really, kept all my data and everything, the modem which is packaged seems pretty average, seem to have 1 less bar of signal than usual, i9100t using on 2degrees, thinking of flashing the old ICS modem back on, but where would one get the files to do this?

Seeing as how you've got the i9100T, you could look at the i9100TDOLP4 modem, which comes from the Telecom firmware package. You could also look at the i9100PBVLP7 modem, which I'm using on 2D on the non-T phone, and it's working fine with good data speeds.

I got an SII around November last year, and pretty much from the start, although not that often, it would just randomly turn off by itself. I would go to pick it up and it would be dead. Re-setting it by hitting the power button at the same time as the volume up for a good 30seconds, reboots the phone.

I have tried a new battery, new sim card and removed the micro SD card..no luck.

Each time it powers off, it will lose between about 15-20% battery life. Sometimes when I notice it's turned off as well, it feels noticeably hot to the touch.

I have done some searching on the internet and not alot of help, apart from it possibly being a prob with it getting stuck in deep sleep mode.

Its just a huge pain as its usually happening at least 1 or 2 times per day, with no warning.

I had exactly the same problem, plagued me for about a year. Eventually I worked out it was Juice Defender. Removed it and it stopped crashing completely. I suspect apps were trying to connect to the net, and being cut off by JD so just ran until they crashed the phone.
